CRYP'llOGRAPH-MACHINEL Specification of Letters Patent.

Application filed August 24, 1907. Serial No. 389,938.

To all whom 'it may concern:

Be it known that I, FRANK R. MCBERTY, residing at New- Rochelle, in thecounty of Westchester and State of New York, have invented a certain newand useful Improvement in Cryptograph-.Machines, of which the followingis a ull, clear, concise, and exact description.

My invention relates to a cryptograpli machine, and more particularly toa' machine for translating a cipher or code reading, representingnumerical values, into the ordinary decimal system of notation.

The object of my invention is to,conceal the translation from theoperator, and to prevent the code reading and the translation fromappearing together, lius rendering impossible any unauthorize attempt atile other uses of my invention may deci hering the code. a.; itreadilysuggest themselves, I will describe it as embodied in andforminga part of a "system of. coin collection, somewhat as follows: Each coinactuated mechanism,

as for example, a coin collector` at a telephone; pay ,stationyisequipped with a counter which gives a code reading instead of the usualreadingin Arabic numerals.` The col- -reading. f The: vtickets wouldfinally lecting agent onfliis tour would collect .the cash andnote on aticket or card the amount thereof, the number of the box Yand the codebe turned in at the lgeneral oilice and the read- '.ings be decipheredby meansof any desired concealed from the operator.

forni of-translating mechanism, such, for

example, as that forming the subject matter o Ithe copendn a plicationof Newman H.' Holland, Sgerial) No. 361,017 filed March 28, 1907. i Byemploying such a inachine, it is unnecessary that the persondeeipliering thev translation be familiar with the code. Forlexample, ifthe code reading is B R N S, by merely operating the corresponding keys,the translation 1706 will be registered.'

It is a particular feature of my invention that 'the translation jof thecode reading is As .a still further precaution, my invention furtherprovides that the ,stub containing the code reading is severed from thepart on which the translation is printed and the two parts are depositedin separate receptacles.

The specific mechanism for laccoliilish drawings, and its scopedetermined rom theA appended claims.

Referring to the drawings z--Figure 1 is y a side elevation, partly insection, of a machine einbodyino' my invention; Figs. 2 and 3 areenlarged fragmentary sectional views of the printing and cuttingmechanisms in normal and operated positions, respectively; Fig. 4 is aview of the card as it appears be- 'fore insertion in the machine; andFig. 5

is a view of the cardafter the translation has been printed, and thestub severed.

Like arts are designated by similar letters oi) reference' throughoutthe several views. Y

A represents the casinff of the machine. VIn Fig. 1, a portion of thiscasing is broken away or shown in section to show the relative locationof the mechanism embodying my particular invention.` As before stated,any suitable mechanism may be used for set# ting the registeringmechanism 1, which may consist of the ordinary digits disks common tosuch mechanism. For sake of clearness, I have omitted all illustrationof the means used in operating said registering mechanism, since saidmeans form no part of my particular invention.

It will be observed that the registering mechanism 1 lies within thevcasing A, an(

hence is concealed from the operator of thev machine. The casing isprovided with un aperture 2 for receiving the card 3. Suid card extendsthrough a carrier l, rests upon a platform 5, and is held in 'suchposition that the code letters on the 4stub of the card are visiblethrough a window 0. The opera tor can then manipulate the translatingmechanism to register the translation on the disks 1. Said disks arelocked in their set positionby a lever 7 a projection of which entersnotches` on the peripherics of the digit wheels, as show:` in Fig. 3.thus holding said wheels in their set position dui-ungr the act ofprinting the translation of the code. The carrier 4 is U-shaped incrosssect'ion, and is open :it ciu-h cud. 'the bottom of the VU Yforminga ribbon plate 8 for the Patented Feb. 21,1911.

type ribbon 9. Said carrier is loosely mountl ed at its lower end upon arocking shaft. 10, which is adapted to be rocked by means of a lever orhandle 11. Inside the channel of the carrier '-1 is a platen 12. Saidplaten is loosely pivoted on the shaft 10 and is normally held against apin or stop 13`by a spring 111.

A lever 15 is fixed at its lower end to the shaft- 10, at the side ofthe carrier 4. By the depression of the operating handle 11, the lever15 is drawn forward. A spring 1G serves to hold the lever 15, the shaft1t) and the handle 11 in the position shown in Figs. 1 and Q and torestore the parts to their initial positions after the operationthereof. livoted at the upper end of the lever 15 is a lever 1T, which,arries a knife Said knife is held by the spring 19 against the plate20, through an opening in which the card 3 extends. A pin 21 on theshaft 10 projects through a hole in the platform 5, so that the platformis reciproeated by the rocking of the shaft 10. Said platform may bemounted in any suitable inanner, as for example, in a slot in apartition lVhen the handle 11 is depressed, the shaft 10 is rocked, thusstarting the knife 1S forward and the platform 5 backward. Upon furtherrotation of the shaft 10, a pivotcd finger 24, under spring tension,engages a pin 25, carried by a rearward projection Q6 of the platen 12,thus moving the platen forward. A slot is provided in the carrier t forthe pin 25. The stub ot the card 8 containing the code cipher is nextsevered by the knife and drops down back of the platen into a receptacle27. The body of the ticket 3 is clamped by the platen 12 against theribbon plate 8 and said parts are then rotated until the type on theregistering wheels 1 project through a'transverse slot 28 and prints thetranslation on the card, the 'card so printed and severed being shown inFig. A further forward movement of the lever 15 allows the finger 24 topass underneath the pin Q5, whereupon the platen 12 is drawn back by thespring 14, thus releasing the card C3. The platform 5, upon which thecard rested when inserted through the opening is now clear. having beenmoved back by the pin QI. The printed card now drops into a receptacle29, said receptacle being separated from the receptacle 2T b v apartition 30. The spring lst returns the platen l2 and the, carrier tagainstthcir respective lstops 13 and 31. l

Pivoted to the carrier 1 is a pawl 32 which engages a ratchet wheel 23?and brovides a convenient meansl for automatically feeding the ribbon ilacross the plate S 'from the reel 34 onto the reel in a manner readilyunderstood from Figs. 2 and 3.

As before stated, when the handle 1l is released, the parts which havenot been already returned to their normall positions, as abovedescribed, are restored by the spring 16.

Since the upper part or stub of the card bears the code reading and thelower part the translation, and the ticket is severed in the action ofprinting said translation, it will be noted that a code reading and itstranslation never appear together except to those who may have access tothe receptacles of the translating machine.

Hence, oppor-v tunitiesfor a leakage of the code are prac` ticallyeliminated.

Having described mechanism embodying my invention, I claim as my owninvention 1. In a translating machine, a casing therefor adapted toreceive a ticket hearing a code reading, means for printing thetranslation of said code reading on a concealed portion of the ticket,and means for severing the portion of the ticket bearing the codereading from the portion bearing the printed translation and causing thetwo portions to be deposited in separate receptacles.

2. In a t'anslating machine, a casing provided with an aperture for theinsertion of a ticket bearing a code reading, wheels adapted to print atranslation of said code reading on a concealed portion of the ticket,means for bringing said ticket into printing engagement with saidwheels, a cutter mechanism adapted to sever the lportion of the ticketbearing the code reading from the portion bearing the printedltranslation, and means for directing the two portions of said ticketinto separate receptacles.

3. In a translating machine, a easing adapted to receive a ticket bxaring'a code reading, wheels adapted to print a translation of saidcode reading on a concealed portion of said ticket, a movable platen forbringing said ticket into printing engagementy with said wheels, acutter mechanism adapted to sever the portion` of the ticket bearing thecode reading and means operating automatically in the movement of saidplaten and cutter mechanism to dii-eet thc two parts of the ticket intoseparate reeep' tacles.

In witness whereof. l have hereunto .suhserihed my name this 3rd day ofAMigust A\. D. 1907.
